Re: [LARTC] HTB + BRIDGE QUESTION!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

["Σταμ?τη? Κεκ??" <skekes@pylones.gr>]

In a bridge you must have also some classes an filters on the second
ethernet interface.
by having the same classes for both network interfaces and to specify
filters to classify the traffic you can control both incomming and
outgoing traffic.
In your policy if you want to limit the traffic to 1Mbit you have to
specify also the same amount as ceil cause ceil specifies the amount of
bandwidth that a class can allocate but when is needed from some other
class then it will be deallocated. Thus you saw too fast downloads. If
you have rate and ceil exactly the same then you make the guarateed to
be the only traffic that must be allocated.
